Question

Two objects are projected at angle theta and 90-theta. The range is equal. Fund relation b/w velocity and max h1 and h2.


it's of projectile motion very tough question.
if you give correct answer then I'll mark you brainliest and then you can give your paytm no ill send 100 rupees..
any irrelevant or spam would be reported

pls answer immediately to get 100 rs..​

Answer 1

Given
Same speed of projection
Angle of projection is θ and 90
o
−θ.
Angle of projection is θ.
Time of flight T=
g
2usinθ
​
....(1)
where u is the speed of projection.
Angle of projection is 90
o
−θ.
Time of flight T=
g
2usin(90
o
−θ)
​
=
g
2ucosθ
​
....(2)
Thus, ratio of time of flight
T
2
​

T
1
​

​
=
cosθ
sinθ
